# ## Program: bird_available
# The program should ask for user to "input a bird name to check for availability" and print a statement informing of availability
# ### create this program with a Boolean function `bird_available()`
# - has parameter that takes the name of a type of bird
# - for this exercise the variable `bird_types = 'crow robin parrot eagle sandpiper hawk piegon'`
# - return `True` or `False` (we are making a Boolean function)
# - call the function using the name of a bird type from user input
# - print a sentence that indicates the availablity of the type of bird checked
